This is a divisional of application Ser. No. 923,604 filed on July 11, 1978, now U.S. Pat. No. 4,206,228, which is a divisional of application Ser. No. 723,826, filed Sept. 16, 1976, now U.S. Pat. No. 4,151,299, which in turn is a continuation of application Ser. No. 565,037, filed Apr. 4, 1975, now abandoned.

The present invention provides compounds of the formula I ##STR5## wherein R₁ represents alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or halogen, R₂ represents hydrogen, alkyl of 1 to 3 carbon atoms, alkoxy of 1 to 4 carbon atoms or halogen, R₇ represents hydrogen, alkyl of 1 to 3 carbon atoms, alkoxy of 1 to 4 carbon atoms or halogen, R₈ represents hydrogen or methyl, the total number of carbon atoms of the substituents R₁, R₂, R₇ and R₈ in the phenyl ring not exceeding 8, X represents ##STR6## wherein each of R', R" and R'" independently represents hydrogen, methyl, or ethyl, and Y represents one of the following groups: ##STR7## wherein Hal is a halogen anion, (b) --O--R₄,

(c) --S--R₄, wherein R₄ represents alkyl of 1 to 6 carbon atoms, alkenyl of 3 to 6 carbon atoms, alkinyl of 3 to 6 carbon atoms, each of them unsubstituted or substituted by a halogen atom, or R₄ represents benzyl or phenyl which independently may be unsubstituted or substituted by halogen or alkyl of 1 to 4 carbon atoms or ##STR8## wherein each of R₅ and R₆ independently represents alkyl of 1 to 4 carbon atoms. The invention also provides a process for the manufacture of these compounds as well as compositions which contain them as active substances and a method of using these active substances as microbicides.

By alkyl or alkyl moiety of an alkoxy group are meant the following groups, depending on the number of the indicated carbon atoms: methyl, ethyl, propyl, isopropyl, butyl, isobutyl, sec. butyl, tert. butyl as well as pentyl and hexyl and the isomers thereof. Alkenyl of 3 to 6 carbon atoms denotes above all allyl, methylallyl and pentenyl; and alkinyl of 3 to 6 carbon atoms is above all prop-2-inyl (propargyl) and but-2-inyl.

By halogens, which can also appear in the hydrocarbon radicals of R₄, are meant fluorine, chlorine, bromine or iodine.

The present invention is based on the surprising observation that compounds with the structure of the formula I have for practical purposes a very favourable microbicidal spectrum for protecting cultivated plants. Examples of cultivated plants within the scope of this invention are: cereals, maize, rice, vegetables, sugar-beet, soya, ground nuts, fruit trees, ornamental plants, but principally vines, hops, cucumber plants (cucumber, marrows, melons) and solanaceae, such as potatoes, tobacco and tomatoes, as well as banana, cocoa and rubber plants.

With the active substances of the formula I it is possible to destroy the fungi which occur in plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of these and also related cultivations of useful plants and also to protect from such fungi the parts of plants which grow later. The active substances act against the phytopathogenic fungi which belong to the following classes: ascomycetes (crysiphaceae); basidiomycetes, above all rust fungi, fungi imperfecti (moniliales); but especially against the oomycetes which belong to the class of the phycomycetes, e.g. phytophthora, peronespora, pseudoperonospora, pythium or plasmopara. In addition, the compounds of the formula I have a systemic action. They can also be used as seed dressing agents for protecting seeds (fruit, tubers, grains) and plant cuttings from fungus infections as well as from phytopathogenic fungi which occur in the soil.

Preferred microbicides are compounds of the formula I in which R₁ represents methyl, R₂ is in ortho-position to the amino group and represents methyl, ethyl or chlorine, --X--R₃ represents the group ##STR9## or ##STR10## and Y, R₇, R₈, R', R" and R'" have the meanings previously assigned to them. These compounds will be referred to as group Ia.

Compounds of the group Ia to be singled out for special mention on account of their action are those wherein R₇ represents hydrogen, methyl, chlorine or bromine, R₈ represents hydrogen or methyl, R' represents methyl, R" represents hydrogen or methyl and R'" represents methyl or ethyl, and wherein Y represents one of the following groups: ##STR11## (b') --OR₄ or (c') --SR₄, wherein R₄ represents alkyl of 1 to 4 carbon atoms, allyl, chloroallyl, 3-methylallyl, propargyl, phenyl, 4-methylphenyl, 4-chlorophenyl, 2,4-dichlorophenyl, 4-tert. butylphenyl, benzyl or 4-chlorobenzyl, ##STR12## wherein R₅ represents hydrogen or methyl and R₆ represents methyl. These compounds will be referred to as group Ib.

An important group of microbicidal compounds belonging to this group Ib comprises those compounds wherein each of R₇ and R₈ independently represents hydrogen or methyl, R' represents methyl, R" represents hydrogen, R'" represents methyl or ethyl, and wherein Y represents --OR₄ or --S--R₄, in which R₄ represents methyl, ethyl, propyl, isopropyl, butyl, sec. butyl or tert. butyl (group Ic).

An important subgroup of microbicidal compounds within the scope of the formula I comprises those of the formula Id ##STR13## wherein R₁ represents alkyl of 1 to 4 carbon atoms, alkoxy of 1 to 4 carbon atoms or halogen, R₂ represents hydrogen, alkyl of 1 to 3 carbon atoms or halogen, X represents ##STR14## wherein each of R', R" and R'" independently represents hydrogen, methyl or ethyl, and Y represents one of the following groups: ##STR15## wherein Hal is a halogen anion, --S--R₄, wherein R₄ represents alkyl of 1 to 6 carbon atoms or phenyl which is unsubstituted or substituted by halogen or alkyl of 1 to 4 carbon atoms, ##STR16## wherein each of R₅ and R₆ independently represents an alkyl radical of 1 to 4 carbon atoms.

A further group of preferred compounds for regulating plant growth comprises those compounds of the formula I in which R₁ represents methyl or ethyl, R₂ is in ortho-position to the amino group and represents methyl, ethyl or chlorine, --X--R₃ represents the group --CH₂ --CON(R")(R'"), and Y represents --S--R₄ and R₄, R₇, R₈, R" and R'" have the meanings previously assigned to them.

By plant growth regulation is meant primarily the retarding control of natural plant development, particularly the desirable reduction of the size of the plant, especially the growth in height. This reduction in growth is observed in mono- and dicotyledonous plants, particularly in grasses, cereal crops, soya or ornamental plants.

The compounds of the formula I are manufactured according to the invention optionally

(A) by acylation of a compound of the formula II ##STR17## with a compound of the formula III ##STR18## or (B) by initial monohaloacetylation of a compound of the formula II to give a compound of the formula IV ##STR19## and by further reaction optionally with a compound of the formula V ##STR20## or with a mercaptan (or the alkali or alkaline earth salt thereof) of the formula

    H--S--R.sub.4

or with thiourea.

In the formulae II, III, IV and V, the symbols R₁ to R₈ and X have the meanings assigned to them in the formula I, and Hal' represents halogen, preferably chlorine or bromine, and M represents a metal cation, preferably an alkali metal or alkaline earth metal cation.

The reaction can be carried out in the presence or absence of solvents or dilutents which are inert to the reactants. Examples of suitable solvents or diluents are: aliphatic or aromatic hydrocarbons, e.g. benzene, toluene, xylene, petroleum ether; halogenated hydrocarbons, e.g. chlorobenzene, methylene chloride, ethylene chloride, chloroform; ethers and ethereal compounds, e.g. dialkyl ethers, dioxan, tetrahydrofuran; nitriles, e.g. acetonitrile; N,N-dialkylated amides, e.g. dimethyl formamide; anhydrous acetic acid, dimethyl sulphoxide, ketones, e.g. methyl ethyl ketone, and mixtures of such solvents.

The reaction temperatures are between 0° and 180° C., preferably between 20° C. and 120° C. It is often advantageous to use acid acceptors or condensation agents. Suitable examples are: tertiary amines, e.g. trialkylamines (e.g. triethylamine), pyridine and pyridine bases, or inorganic bases, e.g. the oxides and hydroxides, hydrogen carbonates and carbonates of alkali metals and alkaline earth metals, as well as sodium acetate. Moreover, in the first manufacturing method, it is also possible to use a surplus of the respective aniline derivative of the formula II as acid acceptor.

The process of manufacture A which proceeds from compounds of the formula II can also be carried out without acid acceptors; in some instances it is expedient to pass in nitrogen in order to expel the hydrogen halide that has formed. In other instances it is very advantageous to use dimethyl formamide as reaction catalyst.

Particulars on the manufacture of the intermediates of the formula II can be inferred from the methods which are generally indicated for the manufacture of anilinealkane acid esters in the following publications:

J. Org. Chem. 30, 4101 (1965); Tetrahedron 1967, 487; Tetrahedron 1967, 493.

The compounds of the formula I in which X= ##STR21## contain an asymmetrical carbon atom (*) and can be resolved into the optical antipodes in the customary manner. In this connection, the enantiomeric D-form has the more pronounced microbicidal action.

Within the scope of the invention, these compounds, their compositions and their use which refer to the D-configurations of the formula I are accordingly preferred. These D-forms usually have in ethanol or acetone a negative angle of rotation.

The pure optical D-antipodes are obtained by manufacturing for example the racemic compound of the formula VI ##STR22## wherein R₁, R₂, R₇ and R₈ have the meanings assigned to them in formula I, and then reacting the compound of the formula VI in known manner with a nitrogen-containing, optically active base to give the corresponding salt. The pure D-form is obtained stepwise by fractional crystallisation of the salt and subsequent liberation of the acid of the formula VI which is enriched with the optical D-antipode and, if appropriate, repeating (also several times) the salt formation, crystallisation and liberation of the α-anilino-propionic acid of the formula VI. From this pure D-form it is then possible, if desired, to manufacture in known manner, for example in the presence of HCl or H₂ SO₄, with methanol or ethanol, the optical D-configuration of the ester falling under the formula II, or with the corresponding amine of formula HN(R")(R'"), the amide falling under the formula II, preferably via the acid halide. A suitable optically active organic base is, for example, α-phenylethylamine.

Instead of the fractional crystallisation, it is also possible to manufacture the enantiomeric D-form of the formula VII ##STR23## by diazotising the amino group in the naturally occurring L-alanine in the presence of e.g. HCl or HBr and thereby replacing it by halogen accompanied by the splitting off of H₂ and with retention of the L-configuration, then, if appropriate, effecting esterification with methanol or ethanol and subsequently reacting the ester with the aniline of the formula VIII ##STR24## when predominantly inversion to the D-configuration of the formula VII occurs (J. Am. Chem. Soc. 76, 6065). In the analogous manner it is also possible to manufacture in this manner the amides in which R₃ =CON(R")(R'"). Irrespective of the cited optical isomerism, an atropisomerism is observed about the phenyl--N<axis in those instances in which the phenyl ring is substituted at least in 2,6-position and at the same time unsymmetrically to this axis (i.e. also on account of the presence of additional substituents as the case may be). This phenomenon is occasioned by the steric hindrance of the radicals --X--R₃ and --CO--R₄.

Also irrespective of the optical isomerism, where R₄ is alkenyl a cis/trans-isomerism can occur in the double bond.

Provided no synthesis with the object of isolating pure isomers is carried out, a product will normally occur as a mixture of two optical isomers, two atropisomers, two cis/trans-isomers or as a mixture of these possible isomers. However, the basically better fungicidal action of the enantiomeric D-form (in comparison to the D,L-form or to the L-form) is retained and is not noticeably affected by the atropisomerism of the cis/trans-isomerism.

The following Examples will serve to illustrate the invention in more detail but do not limit it to what is described therein. Unless stated to the contrary, an active substance of the formula I, which can occur in optionally active form, is always to be understood as meaning the racemic mixture.

EXAMPLE 1

Manufacture of ##STR25## N-(1'-methoxycarbonyl-ethyl-N-methoxyacetyl-2,3-dimethyl-6-ethylaniline. (a) A mixture of 100 g of 2,3-dimethyl-6-ethylaniline, 223 g of 2-bromopropionic acid methyl ester and 84 g of NaHCO₃ was stirred for 17 hours at 140° C., then cooled, diluted with 300 ml of water and extracted with diethyl ether. The extract was washed with a small amount of water, dried over sodium sulphate, filtered and the ether was evaporated. After the excess 2-bromopropionic acid methyl ester had been distilled off, the crude product was distilled in a high vacuum; b.p. 88°-90° C./0.04 Torr.

(b) A mixture of 11 g of the ester obtained according to (a), 6.5 g of methoxyacetyl chloride, 2 ml of dimethyl formamide and 250 ml of abs. toluene was stirred at room temperature and refluxed for 1 hour. The solvent was evaporated off and and the crude product then distilled in vacuo; b.p. 126°-132° C./0.08 Torr.

The D-forms of both cis/trans-isomers (compounds 65 a and 65 b) are obtained by acylating the pure D-form of α-(2,3-dimethyl-6-ethylanilino)-propionic acid methyl ester with methoxyacetic acid or with one of the reactive derivatives thereof.

The other intermediates are also manufactured in a manner analogous to that of Example 1(a), including e.g. the following compounds of the formula IIa (R₁ =2-position): ##STR26##

(a) Manufacture of N-(1'-methoxycarbonyl-ethyl)-N-chloroacetyl-2,6-dimethylaniline.

990.3 g (4.76 g-moles) of α-(2,6-dimethylanilino)-propionic acid methyl ester are mixed with 605 g (5.7 g-moles) of sodium carbonate in 2.5 liters of abs. benzene. To this mixture are then added slowly dropwise 455 ml (5.7 g-moles) of monochloroacetyl chloride in such a way that a temperature of 30°-35° C. in the reaction mixture is not exceeded. After it has stirred at room temperature overnight, the mixture is filtered off and the filtrate is concentrated by rotary evaporation at c. 50° C. The residue is recrystallised from petroleum ether (boiling range 65°-90° C.). Yield: 1132 g of intermediate (m.p. 92°-94° C.).

(b) A mixture of 85.2 g of the α-propionic acid methyl ester obtained according to (a) and 53.7 g of sodium dimethyldithiocarbamate in 1000 ml of acetonitrile was refluxed for 6 hours with stirring and passing in nitrogen. After it had been cooled, the reaction mixture was drowned into water and the reaction product was extracted with chloroform. The chloroform was evaporated off and the product recrystallised from methanol. The white crystals of compound No. 374 melt between 127°-128.5° C.

EXAMPLE 3

Manufacture of ##STR28## N-(1'-methoxycarbonylethyl)-N-([isothiuronium-hydrochloride-S-]methylcarbonyl)-2,6-dimethylaniline.
